      Hi all,

      Can someone point me toward the schematics for the PT100 daughter board? I can't see them on the Github.

      Alternatively looking for an economic MAX31865 card with 400Ohm reference resistors rather than the 430 that seems common on ebay.

      Thanks.

        You can use interface boards with 430 ohm resistors with recent firmware versions because the M305 command accepts an R parameter. However, if you have a Duet WiFi or Duet Ethernet then I suggest you buy the official daughter board to use it with PT100 sensors, otherwise we can't support you if it doesn't work.

          Thanks for the clarification regarding the 430ohm. You may wish to tweek the wiki in relation to connecting PT100 to v0.6 boards - it still suggests a board with a 400ohm reference resistor.

          Where's the schematic for the PT100 daughter boards?

            @doctrucker the temperature daughter board schematics an kiCAD projects are shared on the T3P3 github. Here is the PT100 schematic:

              Thanks. Was looking on the right github but wrong place!
